Researchers at Michigan State University have created TriMag microrobots—microscopic, biodegradable devices designed for precision, minimally invasive medicine. Guided by external magnetic fields, these tiny robots can navigate through the body to reach tumors, blood clots, and delicate eye tissues.

Combining magnetic control, imaging, and localized heating, TriMag enables highly targeted treatments that could replace risky surgeries and reduce side effects. This breakthrough signals a new era of inside-the-body robotics, where diagnosis and therapy happen with unprecedented accuracy.
